Re: Does we have polarization in Aruba?

I am talking about Horizontal & Vertical Polarization. If AP is having only horizonal antenna, and receives a vertical signal there will a loss of signal received by AP, as AP has a horizontal Antenna. Normally i have also heard of AP which has dual polarization enabled!

 

Does Aruba has these features.

Re: Does we have polarization in Aruba?

All outdoor radios and antennas support dual/multiple polarization antennas

Indoor radios at Aruba do not

 

Why

 

Because indoor polarization is of limited beneift due to reflections and can actnually impair the operation of Transmit Beamforming and MU MIMO (as we move towards Wave 2)

 

In addition , the use of directional antennas indoors can negatively impact MIMO, Tx BF, and MU MIMO
